Fuel Pump Sprocket Lock Tool for Mercedes-Benz W654 Diesel

A Mercedes W654 fuel pump sprocket lock tool used to hold the high pressure diesel pump sprocket in place during removal and refitting. It helps keep the sprocket secure while the pump is off, which can avoid turning the job into a larger strip-down than needed.

Used for engine repair, servicing and fuel system work on chain-driven W654 diesel engines, this tool is suited to workshop use as well as more involved garage repairs. When working on the HP fuel pump, holding the sprocket in position is a key part of the job, especially as access can already be awkward with the timing chain at the rear of the engine. It is particularly useful when replacing or refitting the pump on later Mercedes-Benz diesel models where keeping the work controlled saves time and reduces disruption to the rest of the engine assembly.

Covering 1.6L and 2.0L diesel W654 applications, the tool suits engine codes 654.916 and 654.920 and fits a wide range of selected Mercedes-Benz models. The purpose is straightforward: lock the sprocket securely while the pump is removed and then refitted. That makes it a sensible bit of kit for regular maintenance and repair work where avoiding unnecessary dismantling matters. For busy workshop jobs, having the correct locking tool close to hand can also make repeat work more organised and straightforward.
